adapted to be strained in its application to a rail, so that its initial grip will be maintained by spring action, which device may be manufactured with a substantial saving ci material over devices of this gen eral character now in use; which may be readily applied to rails having base `flanges oitl dill'erent widths and thicknesses, and

which when applied to suoli base flanges. will normally stand at substantially 'right' angles to the length oic the rail, though with capacity to take ashaclrle hold on 'the rail base during the presence oit 'a creeping pressure.

. The invention has for further -objects the novel arrangements,constructions and comybinaiiion oi' parts hereinafter more speciiially described and claimed7 for vcarrying out the above stated objects, and such other objects .as will appear from the following The invention is illustrated in certain ypreferred embodiments in the accompanying drawings, wherein* Fig. l is `aplan view oi a rail anchor device constructed rin accordance with the invention, showing the same applied in its operative position on the base flange of a rail. i.

' Lilie characters .of reference designate figures oit the drawings.

Referring first to Figs. l to 3, inclusive, oit the drawings: l0 designates a railroad rail, andll one of the cross ties on which the rail `is supported. I The rail anchor illustrated in these ligures is shown in its operative position on the base flange of the rail,

and preferably comprises a shoe member i2 which fits over one edge of the base flange yot the rail, and a spring `yoke member 13 which engages the opposite edge of the vbase flange and extends around the outer `face of the shoemember. The shoe member isf `preierably angular in cross-section, con# sisting oi" an upperlip lll," which extends .the full length of the shoe and bears upon the upper inclined surface of the rail base, and a verticalweb 15 which engages with lOU `the tie 11.

one ot the Vertical edes ot the said base.-

The shoe is provided at its rorward end with a tie-abuttingI flange 16, adapted to bear against one et the vertical iaces of the crosstie 11, and is also provided at this end with a laterally projecting flange 1'? which extends under the base ot the rail at a pointv adjacent the tie. The web portion 15 oi' the shoe increases in thickness toward the tie abutting flange, so as to provide a wedge surface which intervenes between the edge of the rail and one end oi the spring yoke 13. A pluralityv oi notches 18 are formed on the upper' surtace of the shoe .and are engaged by a portion of the yoke member, as will -be hereinaiterniore specilically described,

so as to lock the yoke in its operative position. rEhe 'yoke member isprei'erably made ot spring` metal, and is termed at one end with a hookproviding a recess 19, which lits over the edgre of the rail base at a point opposite the shoe, the lip E20 or' said hook .being bent toward the tie, so that it will itand at an anglewith relation to the body of the yoke. The other end of the yoke is termed with a hooked portion 21 which lits over the wedge 15 ot the shoe and is formed with a laterally projecting lip 22 which interlocks with the notches .18 oi' the shoe when the yoke is in its operative position. The body portion oitl the yoke, which extends under the rail, is given a torsional or twisted set, so that thehooks at opposite ends ot the yoke will normally stand at an `angle to each other so as to require the yoke to be subjected to a torsional strain when 1t islitted over the shoe member.

The anchor` devicevabove described may be applied to the rail by .first slipping thel .shoe 12 over one edge oi the rail base at a point where the iioot 16 will bear against r1he hook 20 oi the spring yoke is then fitted over the oppositeedge ot the rail base, and the yoke subjected to a twisting strain, as by twisting thc hooked portion 21 in a direction toward the tie. When the yoke is strained in this manner, the lip 22 n'iay be readily passed over the rear end olf the shoe to its desired interlocking position. The spring tension resulting 'from the torsional or twistingaction ofthe anchor during its application to the rail causes the edge of the angular` lipQO to bear with spring pressure against the upper inclined surface ot the rail base, and likewise causes the lip 22 ofthe hooked portion 21 to exert a downward pressure on the shoe member. This spring` tension ojt theyoke operates to hold the lip 141- oi' the shoe in tight lfrictional engagement with the upper surta-ce of the rail, and also prevents the anchor device from being loosened by the vibration of the rail or other disturbing causes. After the `above preliminary engagement has been eilected between the yoke andltheshoe inembers, the yoke member may be moved forward on the wedge 15 ot the shoe, so as to effect a firm transverse grip oi the device on the rail base. By providing the shoe with the wedge surface 15, the anchor may be applied to rails havingbase flanges dit'- tering,` in Width, and permit the yoke 1nember under such conditions to be normally maintained in a position at substantially right angles to the length oi: the rail, whereby a slight creeping movement ot the rail will cause the device to take a iirm shackle hold on the rail. By providing` a spring yoke member with a hook which lits over the shoe, in the manner disclosed in the above figures ot the drawings, it is possible 'to make the shoe member much lighter than is practicable "ith the shoe members of other types et devices of this general character.

1n et to 6 inclusive, a modified form .of rail anchor is shown, in which the hook portion adapted to tit over thev shoe overlaps the edge oit the rail base. his modification consists oi a shoe member 12 which is termed substantiall7 the same as the snee member 12 shown in the preceding iig-lires, with the exception that it i. not provided with notches, as shown in Figs. 1, 2 and 3. The yoke member 13 oit the modification is substantially the same as the yoke 13 shown in Figs. 1, 2 and 3,`with the except-ion that the hooked end 21 is provided with a relatively long lip 2:91a, se that this lip will orerlap the edge ot the rail base and-exert a lirm spring; pressure on the lip 14FL of the shoe 12a. "With this construction it is i'innecessary tor the shoe member v12a to be made so as to accurately lit the base flange of the rail, the spring` tension et the yoke will hold the lip 111iL in tight ti'ctional engage ment with the rail base, even though the distance between said lip 14a and the lower lip 11T be somewhat greater than the thickness et the rail base flange.

The spring yoke 13 is applied to the rail by littinpv the hook end 21." over one edge ot the rail base, as shown in liifr. (i, so as to permit the hook 20 to clear the opposite ede-'e ot the rail. Vlllie hooked end 20"' may then be raised so that the hooked portion can be iitted onto'the rail base by moving the yoke laterally to the lett. rllhe lip 22 ot the hooked end 21a may then be Vliorced over the shoe member, and the lyoke Aorced up on the wedge surface 15"L oit the shoe, in substantially the same manner as that described in connection with the' description et Figs. 1 to 3 inclusive.

liifhile the invention has been illustrated in two speciiic embodiments, it will be obvious that further modifications might be made without departure 'from the invention. 1t
